Kenta Yamashita lifted his maiden Japanese Formula 3 title in style by sweeping all three races at the Sugo season finale.
The TOM'S Toyota driver began the weekend by claiming pole position in qualifying before taking out the first heat from title rival Jann Mardenborough by 1.5s, while Sho Tsuboi finished third.
Yamashita repeated the feat in the second race as he just held off Mardenborugh to the flag by a second.
He saved his best drive for the 18 lap final that saw Yamashita defeat Mardenborough for a third time to claim the championship by three points.
Tsuboi ended the series third in the standings courtesy of third place finishes in the final two races.
Yuhi Sekiguchi has vaulted to the top of the Super Formula standings after scoring his second victory of the season at the penultimate round at Sugo.
The Team Impul racer sprinted into an early lead from pole position after posting a series of fastest laps.
Kazuki Nakajima initially led the chase before a gearbox issue saw him drop to sixth.
However, Sekiguchi's advantage evaporated when the Safety Car was deployed after Joao Paulo de Oliveira lost control and spun into the gravel trap on lap 19.
While his rivals elected to pit under the caution, Sekiguchi missed the opportunity to make his mandatory stop.
Once racing resumed, Sekiguchi continued to set a blistering pace to open up a gap, which allowed the Japanese driver to pit and rejoin in the lead.
He eventually took the chequered flag by 14.2s from Daisuke Nakajima with Tomoki Nojiri third.
Sekiguchi has opened up a 4.5 point lead over Yuji Kunimoto ahead of the double header season finale at Suzuka from October 28-30.
